Each ton of waste circuit boards contains 800 grams of gold, this content is 80

times the native gold ore. The emergence of gold stripping machine, so that

these modern industrial civilization “electronic skeleton” is being transformed

into mobile wealth.


Technological disruption: from chemical baths to

precision surgery


Traditional cyanide gold extraction method is being replaced by modern technology. 

The new bioleaching system utilizes Thiobacillus ferrooxidans, which gradually releases

metal ions at a constant temperature of 35℃, increasing the gold recovery rate to 99.2%

 and shortening the processing cycle to 72 hours. The plasma cracking device instantly

gasifies the non-metallic components at a high temperature of 15,000℃, and the purity

of precious metal recovery reaches 99.99%, with energy consumption reduced by 60% 

compared with the traditional process.


Intelligent control system realizes precise separation. The multi-spectrum recognition

module can analyze the material composition in real time and dynamically adjust the ratio

of leaching agent; the nano-scale filter membrane effectively intercepts 0.1 micron particles

to ensure zero loss of gold ions. Data from a processing center shows that the third

generation equipment equipped with AI algorithms reduces the cost of extracting gold

per kilogram from $38 to $17.


Industrial Reconstruction: New Economy in the

Garbage Heap


Electronic waste is forming a trillion-dollar market. The world produces 53.6 million tons of

electronic waste every year, which contains more than 62.5 billion U.S. dollars worth of gold. 

In the hidden workshop in Huaqiang North, Shenzhen, after the transformation of the

automated production line, can be extracted from 5 tons of used cell phones every day 2.5

kg of gold, equivalent to the proceeds of mining 2,500 tons of gold ore.


Precious metal recycling to promote the rise of circular economy. An Asian country's precious

metal recycling plant, the use of gold stripping machine from the military waste recovery of

platinum group metals, supporting 60% of the domestic demand for precision instrument

manufacturing.


Ecological revolution: from environmental killers to

green guardians


Technological innovation cracks the pollution dilemma. Microwave pyrolysis technology compresses

exhaust gas emissions to 5% of the traditional process, and the electrolytic deposition system

realizes 98% recycling rate of wastewater. Gold stripping unit and photovoltaic power plant form

a closed loop, and the energy consumption per gram of gold is 85% lower than that of mineral mining.


Recycled gold bars from e-waste already account for 12% of the gold trading market in Dubai; gold

extracted from old cell phones is being cast into precision gears in the secret labs of Swiss

watchmakers. These transformations reveal that gold strippers are not only changing the flow

of precious metals, but also reshaping the relationship between humans and resources. When

technology gives waste a new lease on life, every end-of-life cell phone becomes a golden key

to a sustainable future.
